For some reason my battery seems to drain faster than the previous unlock; only while using the phone. The standby battery consumption seems to be a lot better.

my battery backup seems to be lot better now after this update. Previously my battery used to drain even when it was in standby. Now I can say the backup is far better.

I have an iPhone 3GS (3.1.2) which I was using happily after unlock with Blackra1n. Many months ago, I accidentally upgraded it to 3.1.3. Since then it has been a brick for me. I now want to upgrade to ios4 or up. Can anybody help me please. I need to unlock the device most importantly.

I have an iphone 3 and under network, cellular data, you could configure the APN, username/password. I now have an iphone 4.0.1, used jailbreak and ultrasnow to unlock the phone and carrier. now under network, cellular data, it only have option on/off, no where to add the cellular settings. Now I can not access my carrier data network. Is there a way to add the cellular network data settings.

Nishad

my iphone 4 on IOS 4.0.0 was successfully unlocked. somehow, on a trial to reset the phone, it went to recovery mode and itunes has updated it to 4.0.2

I have downgraded to 4.0.1 and jailbrocken! but the Ulstrasn0w is not giving result on my phone now. The moment I insert the SIM, it says only emergency calls.

crytim

same here: have an iphone 4 4.0.1, after unlock sometimes suddenly no cellular network! Happens randomly. Sometimes it works again after restart, sometimes not.
Don’t now what to do?
